Modern water heaters are long-lasting. Unlike appliances such as dishwashers and washing machines, the water heater in your home is for daily use. However, the components installed in a water heater sometimes work too hard, eventually breaking down. When you rely on hot water for cooking, cleaning, and bathing, a minor issue can bring your life to a standstill. Calling an expert for water heater repair in San Jose is the right decision. Many problems are easy-to-handle, and the key to fixing them is identifying the cause. Quick diagnosis and repair can save you from a potentially big hassle.

Here are common problems and solutions.

1. Low Hot Water Supply

A lack of warm water could indicate sediment build-up in your water tank. Minerals such as magnesium and calcium will begin to collect in the water heater base as it nears the end of its life cycle. More the amount of minerals less will be the space to store water in the heater. Flushing your water heater to remove the excess minerals should solve the problem.

2. Too Hot Water

The reason behind this could be the high thermostat setting. The good news is it is easy to fix. Simply turn down the thermostat. However, if the problem persists, check the temperature-pressure valve. If it is broken, the heater will not shut off when it reaches the correct temperature. Since it could be dangerous to change the valve, you should call the best plumbers in San Jose.

3. Leaks

The following problems may cause water leaks:

  • a faulty temperature and pressure (T&P) relief valve
  • irregular water pressure
  • overheating
  • a stuck valve
  • plumbing connection fault
  • loose or damaged heating element bolts
  • a bad gasket
  • a leaking water tank

To resolve this, you can tighten the loose plumbing connection. Next, look for loose heating element bolts and tighten them if necessary. If the heating element leakage continues, you may need the gasket replacement, for which expert assistance is mandatory. Finally, look for leaks on or around the storage tank. Since storage tanks corrode from the inside, you may probably need a water heater replacement.

4. Water Discoloration or odor

Rusty water could be the sign of a corroding tank’s inner lining, which is frequently caused by a malfunctioning anode rod. As a result, discolored water flows. Also, deteriorated anode rode cause cracks, resulting in leaks. Moreover, a decaying sacrificial anode rod emits hydrogen, causing a smell like rotten eggs. You can also check for loose plumbing connections that can be tightened using an element wrench. Consult a skilled water heater expert to see whether changing the anode rod would resolve the issue; if not, you may need a water heater replacement.
